easiest engine swap for a cheeky 'sleeper' on the cheap.

hi looking at a possible project that would not take forever but would leave me with something dare i say 'cheeky' and quite comical to boot. the easier the engine swap the better and the cheaper the better but it has to be servicable for the road and not rusted to death. i know that the brakes and suspension will need looking at too and possibly the donor gearbox to come along with the donor engine.

all ideas welcome.

got 10k in the bank but don't want to spend more than 5k as i am a pikey (honest at least).
